Another thing that doesn't hurt is bringing an extra valve core or two along when going on longer rides.

@jasonwills6694 9 месяцев назад

I started putting a drop of oil on it. Was recommended tip from Silca. Also I have been storing my bike with the valve stems at the top and being careful not to rotate them too much befor inflating before the next ride. This also allows the dried sealent to serve like a tire balancing effect over time with the dried sealent as a bonus. Great video and thank you.

@LifeCycle1978 9 месяцев назад

I would argue putting the valve stem location at the top will leave sealant in the valve. At the bottom, gravity lets it drip out.

@terryg652 9 месяцев назад

@@LifeCycle1978 YES! Putting the stem at the top is going to allow residual sealant to pool and harden IN the valve. If you put the valve at the bottom (or 5'oclock or 4o'clock) sealant can drain out. It doesn't magically jump up into the valve.

@CG-99 9 месяцев назад

This issue is especially a probldm with silca sealant. Silicone or grease on the valve core works really well. Storing the bike with valves at the bottom also seems to help.

@bruceperry1408 9 месяцев назад

@andrewbackhouse5828 9 месяцев назад

Amen to this brother Lama. I discovered this a few years ago and now always have a few dozen spare valve cores in the garage.

@kevwells 9 месяцев назад

Another tip, when pumping up don’t have the value down you up the pressure through the sealant causing it to blob up, also it is likely best practice to not leave the wheels sitting with valves down for long periods of time as when the sealant dries up it dries on the valve core.

@gusoconnor5662 9 месяцев назад

@ArdGeal 9 месяцев назад

I did this a few months back- ordered a load of new valves and keep a couple in the bike spares kit. I store my tubeless bikes with the valves in the 4 or 8 o'clock position to keep the sealant out and before walking away remove the caps and "pop" the valve to clear it. Presta is the problem, and maybe the solution is to just use a brass screw on adapter that turns it into Schrader....

@lifeincycling 9 месяцев назад

For tubeless I started using 76projects no-clog valves (there's also a Filmore alternative from Reserve Wheels) which has been going well so far, for the past year or so. I'm able to inflate tyres faster and there's no separate (and flimsy) valve core to worry about. Only issue is you can't inject sealant through them (as they don't come off) and you have to pop the bead. The stronger sealants (Silca and Stans Race kind) don't like being injected anyway.

@gimjyu 9 месяцев назад

I have a pair of fillmores and they're excellent. But a bit too expensive to get another set. Maybe I'll try the 76projects, it's about half the price - thanks for the recommendation!

@AnAvidCyclist 9 месяцев назад

Came down to make the same comment. Sure Fillmore’s are expensive, but you can fully service them, instead of some cheap product you are waiting to fail and replace. Much more elegant solution to avoid the whole problems the Lama is talking about.

About tpu tubes, Ridenow just recently started to sell tpu tubes with removal valve cores. Mounted them few days ago on my cx winter bike, gonna see how it goes becasue I've had some bent valves on ridenow tubes previously. Hopefully its well made so the casing of valve won't break or the newly mounted valve won't loose air. It's just steal when you can get 2 tubes for 10 USD when on promo, would be even bigger if the valve replacement is working correctly. Will provide updates if this ever happens.

As a machinist and engineer, I just couldn't not appreciate how well thought out and precise they are. Although it's hard to find info on, they can be completely disasembled with a single allen key as long as you're careful to not drop the tiny retention pin, should your OCD kick in and you want to clean them out perfectly. The only real downsides are the price up front and the possiblility of loosing the cap if you're absentminded.

@piast99 9 месяцев назад

But don't overdo the cheapness of the valve cores. Riding along the singletrack I met an unfortunate man with a flat and no pump. I lent him my mini pump with a hose which screws onto the valve. The threads didn't fit, and when I tried to unscrew it the valve broke, half of it was left in the hose. When I poked it out it crumbled under light touch, as if it wasn't made of metal. I ended up sharing my spare valve as well. He told me that those were the factory valve cores and his bike was a pretty decent trail MTB.
